我正在做一个程序,我需要将对象存储在堆栈中。我定义堆栈作为模板类是这样的:使用堆栈来存储对象
template < class T >
class stackType
{
private:
int maxStackSize;
int stackTop;
T *list; // pointer to the array that holds the stack elements
public:
stackType(int stackSize); // constructor
~stackType(); // destructor
void initializeStack();
bool isEmptyStack();
bool isFullStack();
void push(T newItem);
T top();
void pop();
};
这是我的课:
class Matrix_AR
{
public:
float **Matrix; // Matrix as a pointer to pointer
int rows, columns; // number of rows and columns of the matrix
// class function
Matrix_AR();
Matrix_AR(int m, int n); // initialize the matrix of size m x n
void inputData(string fileName); // read data from text file
void display(); // print matrix
};
然而,当我宣布这样
void myfunction(stackType<Matrix_AR>& stack)
{
Matrix_AR item1, item2, item3;
stack.push(item1);
stack.push(item2);
stack.push(item3);
}
我一直得到一个功能错误。我试图修复它五个小时,仍然无法弄清楚。任何人都可以帮忙,请!!!

没有使用[std :: stack](http://en.cppreference.com/w/cpp/container/stack)的任何特定原因? – Collin
